Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To suppress generation of the efflorescence by coloring the color lower in photoreflectance than the uncoated concrete on a concrete wall surface to raise the temperature of the wall surface through absorption of the solar energy. SOLUTION: A precast L-shaped block A for a retaining wall forms a large number of pseudo-stone shaped uneven surface 4 on a concrete wall surface 2 through a joint 3, and the preudo-stone shaped uneven surface 4 is a heat absorptive coloring surface 5 which is colored with the color lower in photoreflectance than the original concrete color.

The design of the wall surface 2 can be diversified by mixing a concrete division exposed surface and a colored painted surface other than the heat absorptive coloring surface 5.  The joint 3 of the uncoated concrete surface is effective for the efflorescence countermeasures, and is also effective for design through the comparison with the heat absorptive coloring surface 5 in the coloring aspect.
